class
ModelRoot
¶ Bases:
ModelNode
A node of this type is created automatically at the root of each model file that is loaded. It may eventually contain some information about the contents of the model; at the moment, it contains no special information, but can be used as a flag to indicate the presence of a loaded model file.

ModelReference
¶ Bases:
ReferenceCount
This class is used to unify references to the same model.

property
fullpath
→ Filename¶ - Getter
Returns the full pathname of the model represented by this node, as found on disk. This is mainly useful for reference purposes, but is also used to index the
ModelRoot
into theModelPool
.- Setter
Sets the full pathname of the model represented by this node, as found on disk. This is mainly useful for reference purposes, but is also used to index the
ModelRoot
into theModelPool
.This is normally set automatically when a model is loaded, and should not be set directly by the user. If you change this on a loaded model, then
ModelPool.releaseModel()
may fail.

getClassType
() → TypeHandle¶
-
getFullpath
() → Filename¶ Returns the full pathname of the model represented by this node, as found on disk. This is mainly useful for reference purposes, but is also used to index the
ModelRoot
into theModelPool
.
-
getModelRefCount
() → int¶ Returns the number of copies that exist of this particular
ModelRoot
node. Each time ModelRoot::copy_subgraph() or make_copy() is called (or some other copying mechanism, such ascopyTo()
, is used), this count will increment by one in all copies; when one of the copies is destructed, this count will decrement.
-
getReference
() → ModelReference¶ Returns the pointer that represents the object shared between all copies of this
ModelRoot
. Since there’s not much associated with this object other than a reference count, normally there’s not much reason to get the pointer (though it may be compared pointerwise with otherModelRoot
objects).
-
getTimestamp
() → int¶ Returns the timestamp of the file on disk that was read for this model, at the time it was read, if it is known. Returns 0 if the timestamp is not known or could not be provided. This can be used as a quick (but fallible) check to verify whether the file might have changed since the model was read.
-
property
model_ref_count
→ int¶ Returns the number of copies that exist of this particular
ModelRoot
node. Each time ModelRoot::copy_subgraph() or make_copy() is called (or some other copying mechanism, such ascopyTo()
, is used), this count will increment by one in all copies; when one of the copies is destructed, this count will decrement.
-
property
reference
→ ModelReference¶ - Getter
Returns the pointer that represents the object shared between all copies of this
ModelRoot
. Since there’s not much associated with this object other than a reference count, normally there’s not much reason to get the pointer (though it may be compared pointerwise with otherModelRoot
objects).- Setter
Changes the pointer that represents the object shared between all copies of this
ModelRoot
. This will disassociate thisModelRoot
from all of its copies. Normally, there’s no reason to do this.
-
setFullpath
(fullpath: Filename) → None¶ Sets the full pathname of the model represented by this node, as found on disk. This is mainly useful for reference purposes, but is also used to index the
ModelRoot
into theModelPool
.This is normally set automatically when a model is loaded, and should not be set directly by the user. If you change this on a loaded model, then
ModelPool.releaseModel()
may fail.
-
setReference
(ref: ModelReference) → None¶ Changes the pointer that represents the object shared between all copies of this
ModelRoot
. This will disassociate thisModelRoot
from all of its copies. Normally, there’s no reason to do this.
-
setTimestamp
(timestamp: int) → None¶ Sets the timestamp of the file on disk that was read for this model. This is normally set automatically when a model is loaded, and should not be set directly by the user.
-
property
timestamp
→ int¶ - Getter
Returns the timestamp of the file on disk that was read for this model, at the time it was read, if it is known. Returns 0 if the timestamp is not known or could not be provided. This can be used as a quick (but fallible) check to verify whether the file might have changed since the model was read.
- Setter
Sets the timestamp of the file on disk that was read for this model. This is normally set automatically when a model is loaded, and should not be set directly by the user.
